Ham?

Astro · Answer

So we know that the potential energy of the apple on the counter is 6 Joules.
The counter is 3.00 Meters high.

The formula for potential energy is pe=mgh   PE=Potential Energy

M=Mass
H=Height
G=Acceleration of Gravity

pe=6 joules
 the h=3.00 meters

6=mx9.8x3

simplify: 6=M*29.4

m=6/29.4

m=.2040816

Round: M=.2KG
Meaning that the mass of te apple is .2KG

No I don't mind, I would like @vocaloid to clarify though. About the GPE and PE

Joe348 · Answer

Astro · Answer

I think it is GPE though because that is when something is positioned above the height of zero
